and has 't'or its object the provision of a new' and improved mechanical inovenieiit applicable'to switches or other devices, hut herein more particularly described in connection this connection.

i have decided to more specilically illustrate my invention herein in connection with a push button wall switch and when so applied it needs but one push huttoiuy which furnishes a novel feature.

Various applications of the invention will he readily apparent, for instance. its use in connection with a pull socket or pendant switch` or devices other than electrical in their nature.

I will describe a forni which my invention mayl take more particularly by referring to the accompanying drawing,` illustrating such a forniy in. which'- i Figure l isa longitudinal sectional view o a switch constructed in accordance with my invention;- Fig. 2 is a view similar to Fig. 1, but showing the switch in a partially actuated condition Fig. 3 is a sectional view on line a-oz of i ig. l, anti Fig. 4 shows the movable switch lelement in its alternative position.

Referringmore particularly to Fig. l, l show a switching' device having a casing l and a front plate 2 adapted to he fastened to the Speeication of Letters Patent.

the position of Fig. 2, at which time the spring' by pulling the push button downwardly causes the trigger G to revolve contraclockwise and permit the pin 5 to fall clown to the bottom wall of the ook` 7, after which time the spring continues to mover the push button i to the right, the pin 5 continuing in its inoveinent toward the right until it has' passed away from the caro :to the position it occupies in Fig. 1, at which tiine it is 65 again ready' toslide over the cam, when the push button is next actuated. The push buts ton also carries ainger S and each actua` tion ot the push button 3 will' caiisethis finger 8 to inoi'e toward* the left and up, 70

wardly until the trigger snaps, at which time there is a downward movement of the linffer which later on continues toward the rigilit hack to the position illustrated in Fig'.

l. This movement of the linger serves to move a switch element 9 through an angle of ninety degrees for each actuation of the push button 3. This switch element is adapted .in the position shown in Fig. 1 to close circuit through stationary contacts 10,.

and il. if the switch element 9 is movedv through an angle of ninety degrees,V (this element always. moving' inl-a. clockwise direction) the circuit through thevcontacts 10= and ll will be opened. A further movementof ninety degrees will again closethe circuit and` so on. Each actuation of the switch element 9 is of course kby snapitictioio,l asv it takes place at that particular time When'the pin 5 trips the trigger 6.v This actuation ofso.

the switch element 9 'is caused by means of a plurality of horizontally extending lingers: l2 which are secured to the switch sleurentt..y

Just before the trigger is snapped theelei nient S rides on' top of one of the lingers l2. so;l

andv its downward movement causes th'ef ninety degree rotation, which at thesaniei tiine releases the element 8 from the finger 12?I` with which it has had engagement. Ofi* course, some means shouldbe'p'rovided 130.100 prevent the element 19 from spinning and"y wall, and having a protruding' push button 3 serving both for make and break purposes. Whenever the push button 3 is pushed in- Wardly itniay, for instancea close the circuit.

suitable trictional nieans such-fas a screw 133iV may be en iployetl or any other vsuitable `de-4 vice to retain the element in its various' pref determined positions.- A stop 14 is provided "10o to prevent complete rotation of -thieleinent 6.

From. what has been described it is thought, the invention will be clear, und also'that it' is capable ot' a great Variety 'of uses and a great diversity of applications.
